Name: elerea
Version: 2.7.0.2
Cabal-Version: >= 1.2
Synopsis: A minimalistic FRP library
Category: reactivity, FRP
Description:
Elerea (Eventless reactivity) is a tiny discrete time FRP
implementation without the notion of event-based switching and
sampling, with first-class signals (time-varying values). Reactivity
is provided through various higher-order constructs that also allow
the user to work with arbitrary time-varying structures containing
live signals. Signals have precise and simple denotational
semantics.
.
Stateful signals can be safely generated at any time through a
monadic interface, while stateless combinators can be used in a
purely applicative style. Elerea signals can be defined recursively,
and external input is trivial to attach. The library comes in three
major variants:
.
* Simple: signals are plain discrete streams isomorphic to functions
over natural numbers;
.
* Param: adds a globally accessible input signal for convenience;
.
* Clocked: adds the ability to freeze whole subnetworks at will.
.
This is a minimal library that defines only some basic primitives,
and you are advised to install @elerea-examples@ as well to get an
idea how to build non-trivial systems with it. The examples are
separated in order to minimise the dependencies of the core library.
The @dow@ package contains a full game built on top of the simple
variant.
.
The basic idea of the implementation is described in the WFLP 2010
paper /Efficient and Compositional Higher-Order Streams/
().
